Gettysburg plans to develop design standards for future construction and renovation projects that incorporate green practices with respect to building site selection, water and energy efficiency, materials, and indoor air quality. The new Center for Athletics, Recreation and Fitness is registered for LEED certification. A structure on the center's roof stores up to 15,000 gallons of water runoff and channels it into the rain gardens for cleansing on site. A large, man-made lake on campus serves as a source of water to replenish the aquifer.
